The tenth or dozenth time Thor forded the stream Muskwa revolted and followed along on his own side.

It was not long before the grizzly returned.
It was soon after this, just as the sun was setting, that the unexpected happened.

What little wind there was suddenly swung straight into the east, and from the western slopes half a mile away it brought a scent that held Thor motionless in his tracks for perhaps half a minute, and then set him off on that ambling run which is the ungainliest gait of all four-footed creatures.
Muskwa rolled after him like a ball, pegging away for dear life, but losing ground at every jump.

In that half-mile stretch he would have lost Thor altogether if the grizzly had not stopped near the bottom of the first slope to take fresh reckonings.

When he started up the slope Muskwa could see him, and with a yelping cry for him to wait a minute set after him again.
Two or three hundred yards up the mountainside the slope shelved downward into a hollow, or dip, and nosing about in this dip, questing the air as Thor had quested it, was the beautiful she-grizzly from over the range.
With her was one of her last year's cubs.
